Revision 59a703eb


Added by aliguori about 11 years ago

Introduce block dma helpers (Avi Kivity)

These helpers perform read/write requests on entire scatter/gather lists,
relieving the device emulation code from mapping and unmapping physical
memory, and from looping when map resources are exhausted.
